Help me solve this equation 3x-7=4x
Sauron [17]
Hey!

Let's write it, 3x-7=4x
Add 7 to both sides,
3x-7+7=4x+7
3x=4x+7
Subtract 4x from both sides.
3x-4x=4x+7-4x
-x=7
Since we don't want a negative variable, we have to divide both sides by -1.
\frac{-x}{-1}=\frac{7}{-1}
Our answer would be,
x=-7

Thanks!
